Technical Field

[0001] The utility model relates to the technical field of palettes, in particular to a palette with a waterproof structure. Background Art

[0002] When creating gouache paintings, it is necessary to mix pigments of different colors according to the painting requirements and dilute the concentrated pigments with water to achieve the color and consistency required for the painting; this step is usually done on a palette.

[0003] For example, Chinese patent CN219154140U discloses a color palette, which has a groove, a color mixing hole and a primary color placement hole in the middle of the top of the palette near one end of the hand-held hole. The primary colors are squeezed on the primary color placement hole, and the colors in the primary color placement hole are transferred to the color mixing hole with a brush for color mixing.

[0004] However, when the paint needs to be transferred outdoors due to weather or other special circumstances, the colors on the palette are easily wetted by rain, which changes the consistency of the paint and makes the paints in various color mixing areas easily mixed.
